Re: [v6ops] [E] New Version Notification for draft-mishra-v6ops-variable-slaac-problem-stmt-01.txt

AFAICS this is a straight violation of the text in RFC 4291 which says that
interface IDs are 64 bits long. As such, I don't see the point in
discussing it unless there is reason to believe that that text will change.

There was a very long and very heated discussion about that text a few
years ago when the 6man tried to take 4291 to full standard. That consumed
a lot of WG time and ultimately resulted in no changes. I expect there are
still going to be very strong opinions on both sides. If we are to reopen
that discussion now, it should happen in 6man, not v6ops. That way those
discussions will at least only happen in one place.
